ICP238I UNIT ADDRESS LIMIT HAS BEEN EXCEEDED FOR THE CHANNEL PATH ASSOCIATED WITH CHPID xx IN CSS y
Explanation
The channel path associated with chpid xx in
CSS y exceeded the maximum number of unit addresses
(devices) allowed for an ESCON or FICON® channel path. See Table 1 to
find the number of unit addresses (devices) for ESCON or FICON channel
paths that your CPC supports.
IOCP might generate more unit addresses for a spanned FC channel path (PATH keyword in the CHPID statement) than for an unspanned channel path. See FC control unit definition considerations:. CSS y is always the lowest CSS ID number in the control unit associated with the channel path and is not necessarily the CSS that caused the error.
System action
IOCP continues to validate and check the syntax of the remaining statements. However, it does not generate an IOCDS and it does not produce configuration reports.
Programmer response
Modify your I/O configuration so that the
CNC, CTC, FCV, or FC channel path does not attach to more unit addresses
than your CPC supports. You can accomplish this task by doing one
or more of the following:
- Reduce the unit address counts of the control units attached to the channel path
- Reduce the number of control units to which the channel path is attached
- For a spanned FC channel path, use the same link address in each CSS of a control unit for the channel path.
